SPECIFICATION forming part ot" Letters Patent No. 267,993, datedNovember 28, 1882,

l Application filed February 15, 1882. (No model.)

Indiana, have invented a new and useful Im' proved Lantern, ot' whichthe following is a full, clear, and exact description.

The object of Iny invention is to facilitate the supply'ot' warm air tothelamp-tlame, and thereby improve the brightness of the light.

The invention consists in a false top forming an air-space in the upperpart of the lantern, from which air space the air is conducted to thelamp by downwardly-projecting aintubes.

The invention further consists invan exterior and an interior chimney inthe upper part of the lantern, which chimneys are covered by a cowlprovided with a side opening and a weathervane, whereby the air inletand outlet can be covered and the wind prevented from passing throughthe opening of the cowl.

The invention also consists in details and parts of construction, aswill be fully described hereinafter.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l` is a vertical sectional elevation'of my improved lantern. Fig.2 is a sectional plan view of the same on line x Fig. 1. Fig. 3 is asectional plan view of the same on the line y y, Fig. l, parts ofthe topofthe lantern being shown in section.

` The lantern-box A is provided with a false top, B', a short distancebelow the top B,where by an air-chamber, G, is formed between the top Band the false top B.l Tubes D extend within the interior of thelantern-box from the airchamber G down nearly to the bottom of thelantern, as shown in Fig. 1. 'A tubular chimney, E', is fixed ou themiddle of the false top B', and a chimney, E, is fixed on the middle ofthe top B, this chimney E surrounding the chimney E a; short distancefrom the same, whereby an annular space is formed between the twochimneys. The inner chimney, E', projects above the outer chimney, E,and is provided at its upper end with an outwardlypro jectin g ange, F,the outer edge of which rests `against the inner surface of a hood orcowl, G,

ittin g over the outer chimney, E, as shown in Fig. 1. This cowl G isprovided at the middle of its top with an externally-threaded tubularprojection, H, through which a vertical pintle, J, passes, which issecured on a cross-piece, K, of the inner chimney, E. The upper end ofthis pintle J is pointed, and on this pointed end of thepintle 'a cap,L, rests,'which cap is screwed on the threaded projection H of the cowlGr, so that this cowl will thus be supported on the pintle, and is freeto turn easily on this pintle.' The upper end ofthe pintle J isthreaded, and before screwing the cap L on the pro jection H a nut, M,is screwed on the threaded end of the pintle J, above the projection H,to prevent the cowl from being lifted off the lantern accidentally.

cowl, the projection H passing through this ring; and the vane is heldin place by the cap L, the lower edge of which rests on the ring N, whenthe cap is screwed on the projection H. The cowl Gr is provided with aside opening, l?, having a wing, Q, at each end.

rior chimney, E', by a series ot' arms, R, attached to both. A shield,S, is suspended from the false top B' above the lamp T. By means of theairchamber G and the tubes D air-ducts are formed, extending from thetop of the lantern to near the bottom of the same.

The operation is as follows: The air passes through the opening P ot'the cowl G, through the air-.chamber C and the tubes I), to the lamp,and the products of combustion pass out through the inner chimney, E',and heat the air in the annular air-space between the two chimneys. Theshield' S throws the heat-rays against the sides of the lantern andagainst the tubes D, whereby the air passing down through these tubeswill be heated, thus causing the light of the lamp T to burn verybrightly. The vane O will always turn the cowl G in such a manner thatthe wind cannot pass through the opening ot' the cowl; but if byaccident a gust of wind should pass into the cowl .and down through theinner chimney, E', it will be delected by the shield S, and cannotextinguish the light of the lamp. All classes of lanterns can beconstructed as shown and describedV above.

Having thus fullydescribed my invention, l

A ring, N,'to| which a weather-vane, 0, is attached, is placed on the vThe `exterior chimney, E, is braced from the inte- IOO claim as newanddesire to secure by Letters exterior chimney, E, the interiorvchimney, E', zo

Patent- 1. The combination, with a lantern, of the false top B and thetubes'D, extending downward in the interior ofthe lantern from theairchamber C, formed by the false top B', substantially as herein shownand described, and for the purpose set forth.

2. The combination, with a lantern, of the exterior chimney, E, theinterior chimney, E',

and the flange F at the upper edge of the-interior chimney, E",substantially as herein shown and described, and for the purpose setforth.

3. The combination, with a lantern, of the exterior chimney, E, theinterior chimney, E, the flange F, and the cowl Gr, substantially asherein shown and described, and for the purpose set forth. 4.l Thecombination, with a lantern, of the the pintle J, the cowl G, providedwith a threaded tubular projection, H, and the cap L, substantially asherein shown and described, and for the purpose set forth. v

5. The combination, with a lantern, of th exterior chimney, E, theinterior chimney, E', the pintle J, the cowl Gr, the cap L, and theweather-vane 0, substantially as herein shown and described, and for thepurpose set forth.

6. The combination, with a lantern, of the 3o exterior chimney, E, theinterior chimney, E', the pintle J, the cowl G, and the nut M,substantially asy herein shown and described, and for the purpose setforth.
